That's correct! Unfortunately bundle sizes also grow accordingly.

That's exactly what's going on. Look at the screenshot in the original post. I technically could do all the assertions after a single render (or two), reducing it to "merely" 600ms excessive wait, but I value DX very much.

TBH you probably hear a lot of bad things about React simply because of how popular it is.

In my project, nearly 900 tests were affected. That’s 4.5 minutes of extra waiting! ⏳
So I built vitest-plugin-react-fallback-throttle, a Vite (and therefore Vitest) plugin that fixes this:

Give it a try and let me know how your numbers improve! 🤓

TIL about the JS "Declarations in Conditionals" proposal
This lets you write const/let inside if/while block
Curious, would you use this?
I think I like it, could make code slightly less verbose and still explicit
(TC39 stage 1, will be presented for stage 2 next week)
